This Brazilian postage stamp features a finely engraved red portrait of Conde de Porto Alegre (Manuel Marques de Sousa, 1804–1875), a distinguished military leader and nobleman known for his service during the Cisplatine and Paraguayan wars. Issued in the early 1940s, the stamp reflects Brazil’s tradition of honoring national heroes through its definitive and commemorative series. The denomination of Cr$10.00 (10 Cruzeiros) indicates it was intended for high-value postal use, often on heavier parcels or international correspondence. Its bold typography and clean frame design highlight both the prestige of the figure and the practicality of the issue. A desirable addition for collectors specializing in Brazilian history, military themes, or mid-20th-century Latin American postal issues.
